again, to remain consistent with [1]}. The lower \(Re\)  branches of Figure REF  (right) are reminiscent of the branch shown in [1]}In fact, the green branch is at the same Reynolds number (\(Re = 60\) ), albeit with different \(k\)  and \(Sc\) ., and the higher \(Re\)  ones are lower amplitude variants of these.
This shrink in relative amplitude can be attributed to the increase in both \(Re\)  and \(k\) , with the latter playing a non-negligible role through the accompanying change in domain size (see Section REF ).
